Me, i find the m50's highs really hard to take. The bass Doesn't have a great deal of texture at all, and i find them really uncomfy. and no detachable cable.

SRH840 is more flat (my ears tell me this) more comfy despite weighing as much as a truck(well...), and more user friendly, with detachable cables. on top of this i find them generally unoffensive, just boring... unfortunately i cant say the same about the M50's.

Thanks, but I really think the comfort will be a problem :/ I don't have a DAC yet or MIDI controllers, so I'll be just laying around anywhere in my house making music (since I have a laptop), I won't always be at my table, so I guess the weight could be a problem...

I guess I'll be so dissapointed when I'm gonna buy some of these (relatively) expensive headphones and they'll sound boring with normal music :D But yeah, my no.1 priority is for them to sound good and flat and everything while I'm monitoring, but I'll have them on my head for a long time and I don't want my head to fall off after like 3 hours of monitoring...

The DT 770 are to bassy to be called a studio monitor. In my experience you'll need a balanced hps to deal with your mix, especially on a bassy music. A good studio hps bass is not overpower bass, you'll need more of a quality bass, and not quantity bass.

The Shure's comfort will be a issue a think because I will be using them for long periods of time, I'm 14 so I have no idea how will they fit on my head, and I'm concerned about those little cables that are exposed near the earcups and hinges. I produce bass-heavy music if that helps. You guys know what makes a good studio monitor headphone. I will be taking them out sometimes and I don't wanna look like a complete idiot wearing them. I'll be maybe even using them for some DJing. I like that the 840 have a removable cable and extra earpads. The same with K271 but they offer velour and pleather pads...GREAT! But I because of their design I guess you can't wear them on the neck, correct? That would mean a "no" for DJing. The M50 looks great but keep hearing that there are better thing out there. I don't like the irremovable cable. I don't know NOTHING about the M-Audio Q40.

Many people who recommend the M50 have never tried another comparable headphone. It's good, but not worth the money it currently commands. For $100 or less, it's decent value.

I woulds say that a headphone with some isolation is best for monitoring in order to keep out unwanted noise, open is an option if you use it somewhere with little ambient noise. However any headphone with a suitably flat sound is a good choice for monitoring.

The SRH840 is the best, imo, but you sacrifice comfort. The SRH840 is quite heavy and may not be suitable for long listening sessions.

Also consider the Beyerdynamic DT880.

And if the SRH840 would be to heavy and uncomfortable (I can't really try them in any local shops) which would be the next best ones, and how much would I sacrifice?
